So
Im in Italy Milan clubbing with some friends and we are from a mix of Germany and UK
Im from UK (British Chinese)

So after the club closes a lot of people were still chatting outside the club and so were we.

This one girl comes bumps into me whilst I was just walking around and says 'this club is terrible' (btw she was quite hot)
I honestly cannot remember what i replied with...

later she approached our group and all my friends were bombarding her with questions..she asked our names and where we were from...

I took a step back and didnt really seem that interested ( I was actually really tired by then) I decided not to give her the attention my friends were giving and asking such generic questions.

she asked us to guess where she was from and my friends just didnt shut up, then she gave us a clue and said shes from Asia, so I said Philippines...I was right

she was half Philippines and half russian.

After that my friends were still trying tro ask questions to start up a conversation and going no where.
she turns to me and we start talking about travelling, she mentions asia and asks me where im from originally..I answered
and then I noticed she was brushing off my friends questions and carried on talking to me so i decided to take a slight interest.

we spoke mainly apart travelling from all types of countries, she shown me pictures of her travels and the spoke about her family and shown my pics of her cousin

and then i show her my pics from africa...

she mentions that we (as in all of us) should go florence for clubbing
at this point she most of spent like 15-20 minutes talking to me whilst my friends where still surrounding her (when i say friends i only knew them from the one person i was travelling with from germany, they clearly couldnt take a hint)

so then her friend comes out of the club and she was with a guy she picked up
and it was clear to me now that she felt lonely because she probably came with her friend and then was left alone as her friend found a guy.

So we kept on chatting with a bit a physical contact whilst describing our stories
then she mentions we should all find another bar or club

and after a little while her friend wasnt seemed pissed off with the guy and asked her to leave with her

so said ok we should stay in touch find me on fb, took my phone and typed her name in..saying I should go to florence sometime

she left

my friends all gave me a hard time about how i didnt 'seize the opportunity'
dont get me wrong I would have gone home with her , but i was so tired and i really could not be bothered with all the effort i was ok with just a contact close.
i was ok with making a friend i can chat to on fb or SPAM or whatever and maybe in the future she would come to uk or i would go to florence
soooo.

I added her on fb a few days later and sent a nice message..'it was good to meet you..bla bla bla' and added a few of the stuff we spoke about for jokes.

She hasnt replied or accepting...its been a week
now im a bit confused because she seemed a lot more interested and took initiative than i did

Am I missing something here? Im not really too bothered about it but id like to here your opinion on the situation
